    • A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.
    • 公开了一种用于将润版流体施加到可变数据光刻系统中的成像构件的可再成像表面的系统和相应方法,而没有成形辊。 在一个实施例中,该系统包括用于将润湿流体从液相转化为分散流体相的子系统,并且用于将包含分散流体相的润版液的分散流体的流动引导到可再成像的表面。 阻尼流体直接在可再成像的表面上回流到液相。 在另一个实施例中,连续的润版液体带可以直接施加到可再成像的表面。 该实施例包括具有端口的主体结构,该端口用于将连续流体带中的阻尼流体直接传送到可再成像的表面,以及与主体结构相关联的机构,用于当可再成像的表面处于可再成像的表面时,将夹带的空气层剥离在可再成像的表面上 运动。
